Venice the weather and what to wear

Can anyone predict the weather?

None of us earthlings; at least not that far ahead

would a trench coat or umbrella be wise?

I would be inclined to do an umbrella vs a trench coat

What warmth of clothing would you take

I would probably be happy with short sleeve shirts during the day. Windbreaker weight ( light) jacket for night

I need to know the exact date in April to give you an accurate forecast hour by hour. While I await your precise travel dates, I suggest you pack a small pocket umbrella, as April has changeable weather and a chance of rain on any given day. But if you forget to pack one, do not despair. The minute the first rain drops start to fall, there will be scores of African street vendors, magically appearing from nowhere, all with plenty of portable umbrellas for sale. If you know how to bargain hard, you can secure one for less than €5. Dress in layers. Days may be warm but evenings get cool.

Please think twice before you take an umbrella into the compact masses of people you see in Venice. I have had too much experience fighting to keep the points away from my eyes. Use a light rain jacket and a (baseball) cap instead.

No one can predict the weather accurately. These days, average statistics are pretty useless, as extreme weather is becoming the norm. For example, this time last year we had lots of snow and ice and there has been hardly any this winter. January had half the average rainfall.

Another vote for no umbrellas - take a coat with a hood.

Take layers of clothes. Decide what to take the day before you travel by looking at the weather forecast for the first few days. I always take a checked bag, so I am always covered for different weather, as I am not restricted to whatever needs to be squeezed into hand luggage.

We were in Venice towards the end of May. Even then, we had a couple of cold and rainy days. We were good layered with waterproof windbreakers and sweaters. Our biggest concern was our feet. We only had one pair of shoes and didn't want them to get wet. We solved this by buying these incredibly ugly but oh-so-functional neon-colored vinyl boots that pulled over our shoes. They were 10 euros on some street corner. We sloshed all over town and had dry shoes for the rest of our trip. While an interesting fashion statement, they are worth considering.

I like the wonderground.com website for looking at expected weather based on past years and current trends. You just put in your dates, look at a few years, gives you a sense of the range and variability to expect. And I have my own "souvenir" rain boots from my last Europe trip!

no one knows I'm afraid. I've been in Venice in April in short sleeves and been in Venice in April feeling cold in long sleeves and a coat.

Whatever the weather it is a wonderful place.

The above advice for windbreaker and short sleeves is decent advice.

The day before you depart, check the weather forecast for Venice online and you can adjust your wardrobe up to the last minute.

When we were there in late April, it was warm and sunny. They have umbrellas there if you need one. A trench coat would be a heavy nuisance to carry about the while trip. A lightweight foldable rain jacket is something I pack for everywhere, anytime.

I think lightweight rain jacket and maybe buy umbrella and/or rubber boots to go over shoes when I'm there , win out. Plus short and longsleeve shirts and sweater. Does that seem right? If it rains everyday what do you do with your time, just walk around in the rain all day? How likely is flooding in April? My days there will be 14th through the 24th.

We found Venice to be magical in the rain. There's plenty of museums and churches to get out of the rain. We went to Murano on the vaporetto one cold, wet day and it was wonderful. No crowds, empty streets and we walked around the island to places most don't go. If you are prepared for the weather, it isn't a problem.

That's good to hear. Thanks.

I believe the best ( and I use that word loosely) is to look at the past - and plan on it to be different. How much - is the question.
